COUPLER RELEASE: arcems.

Application Qfiled June 22, 1923. Serial No. 646,995.

To aZZ whom it may concern: .1.

Belt known that I, STERLING 11. 0am. BELL, a citizen of the United States ,of America, residing at the city of St. Louis, State of Missouri, United States of America, have invented a certain new and useful Coupler Release Rigging, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the ac-, compa-nying drawings, forming part of this specification.

My invention relates to a coupler release rigging and particularly to improvements in that form of rigging shown and described in Patent No. 1,453,002 granted to me April 24., 1923.

One object of the present invention is to so construct the device that the member for securing the link to the operating arm may be attached to the link after the latter is in its completed form.

Another object of my invention is to provide the type of release rigging with a link, the elongated loop of which has a head of such size that it cannot pass through the eye of the coupler lock pin, thus positively preventing disengagement of the loop from the pin at any time when the link is connected to the operating arm. In the accompanying drawings which illustrate'one form of release rigging made in accordance with my invention Figure 1 is a top plan view of a portion of the end of a railway car to which my device is applied; Figure 2 is a front view of the link together with the cooperating parts; Figure 3 is a view of the connecting member in the open position, and Figure 4 is a View, partly in section, of the connecting member and the end of the operating arm to which it is applied. 5 indicates the end of a railway car on which a rock shaft 6 is mounted by means of brackets 7. One end of the rock shaft is provided with a handle 8, and the other with an operating arm 9. The end of the arm 9 is flattened as indicated at 10 to provide an enlarged portion in which is formed a horizontal eye 11. The connecting member for securing the link to the operating arm consists of two similar parts 12 pivoted together by means of a rivet 13 so that the parts may be swung apart as shown in Figure 3, or moved into parallel position as shown in Figure 4.

When in the latter position a rectangular .opening 14- is formed between them.

The stem 15 of the link is rectangular in shape and slightly smaller than the opening 14: so as to slide freely in the latter. The upper end of the link is turned over at 16 so as to rest on the upper edge of the operating arm, as in my prior patent above referred to, and the lower end is formed into an elongated loop 17 adapted to engage with the eye of the coupler lock pin 19. In the present construction, however, the loop 17 terminates in a head 18 of such size that it will not pass through the eye 19. This head 18 may be formed by bending over the end of the loop as shown in F igure 2.

The ends of the members 12, when in parallel position, form a stud adapted to pass through the eye 11 of the operating arm and are threaded, as indicated at 20 to receive a retaining nut 21 adapted to bear against one side of the flattened end 10 of the arm, the other side bearing against a plate 22 formed by flanges on the members 12. The outer ends of the threaded parts 20 are cut away to form a slot 23 so that the ends of the stud may be spread by the insertion of a suitable tool to prevent the nut 21 from coming off the stud. As it is necessary for the studto have a rocking motion in the eye 11, the nut 21 should not be tightened sufiiciently to prevent this movement.

In applying my device the link 15, which may be completely formed before application, is threaded through the eye of the look ing pin 19, the end 16 being capable of passage through the eye. The connecting member is then opened, as shown in Figure 3, and then closed around the stem 15 of the connector, after which the stud of the connector is passed through the eye 11, the nut 21 applied and the end of the stud spread to prevent the accidental disengagement of the nut.

Having fully described my invention, what I claim as new and desire to secure by Let ters Patent of the United States is:

1. In a device of the class described, the combination with a. coupler lock pin, of an operating arm therefor, a link extending between said parts, and a connector formed of two parts adapted to be applied to the stem of the link and engaging the operating arm.

2. In a device of the class described, the

combination with a coupler lock pin, of an operating arm therefor, provided with an eye, a link extending between said parts, and a connector comprising two parts cooperating to form a stud engaging with said eye, and an opening for the stem of said link.

3. In a device of the class described, the combination with a coupler lock pin, of an operating arm therefor, provided with an eye, a link extending between said parts, a connector comprising two parts cooperating to form a threaded stud engaging with said eye and an opening for the stem of said link, and a nut engaging said threaded stud.

4. In a device of the class described, the combination with a coupler lock pin, of an operating arm therefor, a link extending between said parts, and a connector comprising two parts pivoted together and engaging said arm and providing an opening for the passage of the stemo'f said link.

5. In a device of the class described, the combination with a coupler lock pin, of an operating arm therefor, provided with an eye, a link extending between said parts, a connector comprising two parts pivoted together, said parts cooperating to form a threaded stud engaging said eye and a passage for the stem of said link, and a nut engaging said threaded stud.

6. In a device of the class described, the combination with a coupler lock pin, of an operating arm therefor, a link extending between said parts and terminating at the lower end in an elongated loop having an enlarged head, and a connector comprising two parts surrounding said link intermediate of the ends and engaging said operating arm.

In testimony whereof, I have hereunto set my hand and aflixed my seal.
